the dealer put one in my car and it is still running rich and stalling and is loud. rpm gauge has also quit working. I was told years ago that after market parts are not compatable with this car because it has a 3.1 and they did not make very many of them. Is this true? Dealer is now guessing at problem and I know it is the distributor. I have been only owner of this car. I know my car. The people working on car a very young and now they keep guessing at things and my bill keeps getting higher. They replaced ekg valve and still no difference. Your help will be greatly appreciated.

Yes, aftermarket distributors will work just fine with your car. Many Firebirds of that year came with the 3.1L motor, it was the standard engine.
I don't really see the distributor as being the cause for it running rich. Seems to me like it would be more of an injector issue (leaking, spray pattern, etc...) or even a faulty sensor (oxygen, etc...)
